Change screen frame rate

OS (e.g. Win10): Win11 Pro
PsychoPy version (e.g. 1.84.x): 2021.2.3
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?: I make some changes that should happen on each frame, but the current pace of changes is too fast for my purposes. Is there a way to access the frame rate with which the stimulus is shown? or else is there a way to choose the updating of my stimulus to happen over more than one frame?
